KEYBOARD-OPERATOR.

SPECIFICATION forming part of Letters PatentNo. 730,504, dated .T une 9,1903.

Application filed February 4, 1903. Serial No. 141,912. 4(No modali) l across-section of any other shapesay a rec- To CLZZ whom it may con/cern:

Be it known that I, OTTO ADOLF WOLTERS, merchant, a subject of theEmperor of Germany, residing at Lemfrderstrasse 5, Hanover, Germany,have invented a certain new and useful Keyboard-Operator; and l dohereby declare the following to be a full, clear,an d exact descriptionof the invention,such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to a driving mecham ism for operating machines orinstruments of all kinds that are set in motion by keyboards,key-levers, or the like by means of a perforated record-strip. Theprincipal part of the mechanism consists of two disks or two pairs ofdisks placed concentrically one above the other. One of these disks orpair of disks serves as a magazine containing pins in correspondingborin gs, which'being lifted through the holes in the record-strip by amagnetized comb are received in perforations in the sec# ond diskregistering with the borings of the' iirst disk and carried past a setof levers, one of which is moved by the pin projecting out of the disk,and thus transmits its motion on toV the keyboard. After having passedthe levers the pins raised by the magnetized comb are pressed down againinto the magazine-disk by a second comb.

Referring to the accompanying drawings, Figure l is a vertical section,Fig. 2 is a side elevation, and Fig. 5 is a plan view, of an apparatusconstructed according to the present invention. Fig. 4: is adiagrammatical plan view of a modification, showing a pair of disks.

Referring to Figs. l to 3, on ashaft a are iixed two disks b and c,which revolve in the same direction and with the same velocity at asmall distance one over the other. In the lower and thicker disk bborings d are provided, containing pins e, Fig. l, the borings d beingarranged radially, as shown in Fig. 3. The upper and thinner disk ccontains rows of holes exactly registering with thc borings in the lowerdisk. As shown at j) in Fig. 3

by dotted lines, the borings (Z and holes of each row may be alternatelydisplaced, whereby a greater number of holes can be provided in eachrow. The holes, borings, and pins may have a round cross-section, asshown, or

tangular one. l

rlhe perforated record-strip g, made in a well-known manner by means ofa perforatin g-machine, moves between the two disks on one side of theshaft a from the spool 7L to the spool 1l, its speed being so adjustedthat the perforations placed on the same transverse line on therecord-strip register exactly with a row of borings and holes in thedisks b and c at the time when such row arrives under the comb 7c, beingthe position shown in Figs. land 2. This comb is moved up and down by acam Z and moves upward at the moment when a row of perforations arrivesunder it, and as a perforation in the record-strip registers at the sametime with. the borings and perforations d and f in the Vdisks, Fig. l,the comb k, being magnetized for the purpose, raises the steel pin e,which registers with a perforation in the record-strip altogether out ofthe boring of the lower disk b, so that it is carried on by the disk c.For the purpose of preventing the pin from falling back prematurely intothe corresponding boring of the disk b a disk'm, of brass, is providedbetween the disks band c, which is provided with a row of holes only inthe section plane shown in Fig. l. The pin accordingly rests on thestationary disk m and is carried on by the disk c past the set of leversn and sets the lever corresponding to it in motion. This motion istransmitted in any known manner v to the keyboard of the instrument ormachine to be operated by the present mechanism.

The raised pins are pressed down again out of the disk c into the disk bby a comb o, which moves up and down simultaneously with the comb 7c,but is not inagnetized. The disk nml beingprovided with a second row ofholes under this comb, as soon as the perforations d and f in the discsregister with the row of holes in the stationary disk m the comb o movesdownward and forces the raised pins down into the corresponding borings(l. The motion described is continually repeated as often as the disks band c advance a row of perforations under the comb 7c.

As shown by Fig. 4, instead of a disk b and a disk c two pairs of disksmay be arranged opposite each other, in Fig 4L only the upper pair ofdisks c c2 being visible. Then the record- ICO strip g moves between theshafts a' a2 of the pairs and the disks b' c at the left hand work onthe one half of the strip and the disks b2 o2 at the right hand on theother half. Thus the disks can be made of half the diameter of the disksshown in Figs. l to 3 and can be moved more quickly, and thereforeprovided with a lessnumber of radial rows of holes.

The described driving mechanism is applicable to a great many differentuses, and especially to operating type setting and forming machines, andit can also be used for operating musical clocks worked by means of of aperforated record-strip.

Having now particularlydescribed and ascertained the nature of my saidinvention and the manner in which it is to be performed, I declare thatwhat I claim isl. In a mechanism for operating machines or instrumentsby means of a perforated record-strip, the combination with a movablemember, of pins carried by said member, a second movable member arrangedadjacent to said first-named member so as to allow the passage of arecord-strip between. said members, perforations in said second membercorresponding to the pins in said first-named member, means 'for movingsaid pins through the perforations of the record-strip into theperforations of said second movable member, and operating connectionsactuated by said pins.
